If I code a button widget like this (I'm using the version
of GTK that came with Fedora Core 5)...
GtkWidget *B = gtk_button_new_with_label (Label);
g_signal_connect (GTK_OBJECT (B), "button-press-event",
G_CALLBACK (Happened), "HELLO");
and the callback is this...
Happened (GtkWidget *W, gpointer Data) {
g_print ("ButtonHappened...|%s|\n", (char *) Data);
}
when Happened is executed, it doesn't print the data. That is, I get
"ButtonHappened...||". But when I replace the parameter
"button-press-event" in the call to g_signal_connect with "pressed",
on execution the printout is as desired, "ButtonHappened...|HELLO|".
Now, "button-press-event" is in lists of event types such as you
find in the GTK 2.0 tutorial at
http://www.gtk.org/tutorial/a2769.html
As for "pressed", I don't know where I got it. It must have
come along with some example I found in a newsgroup or on the Web.
I haven't been able to find an event-type list anywhere that
contains it, so I can't solve the mystery of why I get what I
want when I use that parameter, but not with the "legitimate"
parameter.
